Answer:
0.8188 or 82%
0.0000643
Step-by-step explanation:
Given that engineering specifications on the shelf depth of a certain slug to be turned on a CNC lathe are from .0275 in. to .0278 in.
If x is the dimension then X is N(0.0276, 0.0001)
Or 
is Normal (0,1)
a) Fraction of shelf depths are in specifications
=
b) For 98% to be within the specifications,
Margin of error = 
For 98% critical value Z two tailed is 2.33
Hence std error = 
So sigma should be = 0.0000643
Answer:
2400 coins
Step-by-step explanation:
What we should do is calculate the Least Common Multiple of 80 and 75, since each of us put together a group with this amount of coins, this way we will know the amount of coins when they are equal.
To obtain the L.C.M
you have to factor both numbers and multiply the numbers whose exponent is the highest, it looks like this:
75 = 5 ^ 3
80 = 2 ^ 4 * 5
We multiply those with the highest exponent,
5 ^ 3 = 75
2 ^ 4 = 16
75 * 16 = 1200.
L.C.M. is 1200.
Since they tell us that they have less than 2000 coins, this is the correct answer, because when assembling these groups in this way, they coincide again in 2400, which is over the limit.
So, each one has 1200 coins, in total it would be:
1200 * 2 = 2400
Between them they have a total of 2400 coins
Answer:
15.6
Step-by-step explanation:
the traingle is right so u have to apply the pythagorean theorem to find x so x^2=10^2+12^2=244
so x=15.6
Answer:
O C. 0
Step-by-step explanation:
What is the sum of 15 and its additive inverse?
In Mathematics, the additive inverse of a number is defined as the number that when it is added to a specific number equals 0
From the above question, the additive of 15 = -15
Therefore, the sum of 15 and its additive inverse is calculated as:
15 + -15
= 15 - 15
= 0
Therefore, Option C is the correct option
